Single-Hung Windows

As one of the most popular window styles across the country, single-hung windows are classic and timeless. They feature a fixed top sash so that only the bottom portion of the window is able to be opened. 


Since the top of the window is fixed, this is a great energy-efficient option as it’s less susceptible to air leaks.

While double-hung windows look very similar to single-hung models, the key difference is that you can raise and lower both the top and bottom sash. This makes it a great option for homeowners who want to enjoy plenty of fresh air flowing into their homes. 


As an added bonus, double-hung windows are easy to clean, thanks to the tilt-in sashes. 

Picture Windows

If you really want to enjoy the view from your home, consider installing beautiful picture windows. Although they don’t open, they offer an unobstructed view of the outside world, letting extra light stream into your home. 

Bay Windows

Bay windows protrude out of your home, instead of being flush with your siding. Made from a central picture window which is flanked by more narrow windows on each side, they offer a unique design that can boost your curb appeal. 

Bow Windows

Bay and bow windows are often thought to be the same, but their construction is what sets them apart. Bow windows are made from three or more window panels, all of the same size. While bay windows have a boxy look, bow windows tend to look more curved. 

Casement and Awning Windows

Both casement and awning windows are hinged, allowing them to open for maximum ventilation and light. Casement windows have hinges installed on either the right or left side of the frame, while awning windows have hinges installed at the top of the frame. 


If your window opening is taller than it is wide, then casement windows are a great option. If it’s wider than it is tall, then awning windows are a better choice for your space. 

Hopper Windows

Are a great option for basement windows. These small windows provide extra light and ventilation in these smaller spaces and open inward, which is ideal for tight areas. 

Acrylic Block Windows

Finally, acrylic block windows are a popular option in homes with windows directly above the bathtub. While you likely want plenty of natural light flooding into your space, you also want your privacy while you bathe. 


Acrylic block windows are the perfect solution, as they are made with resin so they are not see-through.

Sliding Windows

If you like the look of a big picture window, but you want to have the option to open it, consider installing sliding windows in your home. Unlike single-hung and double-hung windows, which open vertically, sliding windows open horizontally.


Homeowners love them because they are easy to use and they offer an unobstructed view of the outside world.

Garden Windows

Do you have a green thumb? If so, consider your plants when replacing your windows. Much like bay and bow options, garden windows protrude out of your home. What sets them apart, however, is that garden windows come with space for shelves so you can give your plants plenty of sunlight. 

Specialty Windows

Also known as architectural shape windows, these are designed to fit within unique spaces around your home. For example, if you have a bonus room with an angled ceiling, these windows can be ordered to fit the specific dimensions of the space.
